Thanks for the report and the fix.
Octave 4.2.2 is no longer in development. Re-targeting to the current stable branch which is Octave 6.0.90.

This looks like a typo to me. See also the Mathworks documentation:
https://de.mathworks.com/help/matlab/apiref/mxgetnan.html

Fixed on the stable branch which will eventually be released as Octave 6.1:
https://hg.savannah.gnu.org/hgweb/octave/rev/2c607b7ecee9

Closing as fixed.

When using mexGetNaN, the compiler complains.

In file included from fillmissing.c:24:0:
fillmissing.c: In function ‘mexFunction’:
/usr/include/octave-4.2.2/octave/mex.h:83:19: warning: implicit declaration of function ‘mxGetNan’; did you mean ‘mxGetNaN’? [-Wimplicit-function-declaration]
 #define mexGetNaN mxGetNan
                   ^
fillmissing.c:148:22: note: in expansion of macro ‘mexGetNaN’
             vro[0] = mexGetNaN(); /* initial value */

Replacing the line with the following fixes the problem.

 #define mexGetNaN mxGetNaN
